This invention relates to folding boxes and has for an object'to providea box structure including a bodyxand a sliding cover, the body beingfoldable to provide a closed compartment "and an open compartment.

Another object of the invention is to provide a folding box having arectangular body with a standard folding end and with a speciallyconstructed folded end arranged to provide an open compartment with thewalls automatically locked as-soon as'the parts have been folded.

Anadditional and more specific object of the invention is to provide afolding box wherein the upper and lower panels are provided With exten-'sions adapted to be folded and interlocked to provide with the side ofthe box a rectangular open compartment.

In the accompanying drawing- Fig. 1 is a perspective view of a foldingbox disclosing an embodiment of the invention, part of the body beingshown as pulled out of the cover;

Fig. 2 is a top plan view of the body of the box shown in Fig. 1;

Fig. 3 is a transverse sectional view through Fig. 2 on the line 3-3;

Fig. 4 is a longitudinal sectional view through Fig. 2 on the line 4--4;and

Fig. 5 is a perspective view of the body shown in Fig. 2 with the endsunfolded and spread out more or less.

Referring to the accompanying drawing by numerals, indicates arectangular slide which 35 may be made .of pasteboa-rd or other suitablesheet material and 2 the body of the box also formed of pasteboard orother suitable material and constructed in one piece. The body 2 isformed from a single blank folded to present a rectangular centerportion having a top panel 3, a bottom panel 4, and side panels 5 and 6.A slot 1 is arranged at the juncture of the top panel 3 and the sidepanel 5, whereby articles may be discharged into the closed compartment8. As

5 shown in Fig. 4, the open compartment 9 is arranged at one end of thecompartment 8.

It will be understood that the box may be used in connection with anydesired article, but it has been designed especially for safety razorblades.

50 Usually a package of unused razor blades is deposited in thecompartment 9 and when a blade is used it is discharged through slot 1into the compartment 8 where it remains until some convenient time whenthe owner of the box may 58 open up the end I0 of the compartment. The

endlfl is a conventional folding end for folding boxes and consists oftabs and I2 which are extensions of side'panels 5 and B and an extension|3' having a section I4 and a tuck-in tab l5. When this end is to beclosed, the tabs and I2 are swung toward each other and then the panelI4 is swung against the folded device. After this has been done, thetuck-in tab I5 is arranged as shown in Fig.4 and'the end is closed. Theend l6 which is opposite toend lfl'is of a very special construction andforms part of the open compartment 9.

As illustrated particularly in Fig. 5, panel 5 is provided with anextension I! while the panel 4 is'provided with an extension IS. Theextension I! is'formedwithsections l9 and 20'and a tab 2| while theextension 18 is formed with sections 22"and' 23 and a tab 24; Thesection 22 isprovid'ed'with a pull tab 25 which maybe positioned asshown in Figs. 1, 2 and 4 or may be allowed to stand upright. This tabis used for sliding the body 2 in and out of the slide cover I.

After the parts have been constructed as shown in Fig. 5 and it isdesired to fold the body, the section I9 is swung downwardly to form oneend wall of compartment 8, as shown in Fig. 4, and section 20 isarranged parallel to and contacting with the bottom panel 4, after whichthe tab 2| is arranged parallel to the wall or section l9 and tabs 26and 2! folded so as to extend toward each other. The section 22 ofextension I8 is swung to extend at right angles to the bottom panel 4and then section 23 is swung downwardly over the tabs 2|, 26 and 21. Thetab 24 is then moved to a position parallel to the bottom panel 4 andthe folding operation is completed. By folding the parts in this waythey interlock and remain in this position until positively 1 movedtherefrom.v After the extension IT has been folded, the tabs 26 and 21are folded against the tab 2| and then extension I8 is folded as justdescribed so that the ends will be very strong and the parts fullyinterlocked while providing an easily engaged pull tab 25 whereby thebody 2 may be readily slid into and out of the slide cover I.

I claim:

1. A box blank adapted to form a rectangular closure having a closedcompartment and a compartment having one open side, said blank includinga rectangular body, a pair of rectangular side panels extendinglaterally from opposite sides of said body, each of said side panelshaving a tab at each end, said body having at one end a closure sectionprovided with a locking tab and at the opposite end an extension havinga pair of folding sections and a tab, each of said folding sectionsbeing of equal width and equal to the height of said side panel, arectangular top panel extending laterally from the side edge of one ofsaid side panels, said top panel extending from one end of thelast-mentioned side panel but falling short of the other end, anextension from said top panel parallel and in contact with thelastmentioned side panel, said last-mentioned extension having a pair ofsections of equal width equal to the height of the side panels, and asecuring tab extending from the edge of said top panel opposite the edgemerging into the last-mentioned side panel.

2. A folding box including a body having a rectangular tubular portionprovided with top, bottom and side panels, one end of said body having apair of tabs extending fromv said side panels and an end sectionextending from said bottom, said end section being provided with an endclosure sectionhaving a locking tab, the tabs of said side panels beingfolded toward each other and the end section being folded over saidfolded tabs While said locking tab extends over said tabs into thetubular portion for holding the parts in their folded position, saidside panels at the opposite end having a pair of tabs adapted to befolded toward each other when the box is closed, said top and bottompanels at said opposite end being provided with extensions, each of saidextensions having a pair of folding sections and a tab at the end, theextension from the top panel having one section formed of the top panel,said extension being of a width equal to the height of the side walls, asecond section equal in width to the distance between the end of the toppanel and the end of the side panels, the first section being folded ata right angle to the top panel to form a divisional wall while thesecond section is positioned flatwise against said bottom with the tabon the end thereof folded upwardly against the inwardly extending tabsof the side panels, the extension of the bottom portion of the bottompanel having two sections each equal to the height of the side panelsand a tab equal to the distance between the end of the top panel and theend of the side panels, said bottom extension being folded over andstraddling the tabs of the side panels and the tab of the top panelwhile the tab of the bottom extension fits flatwise between the sidewalls against the section of the extension from the top panel.

'3. A box of the character described including a body having top, bottomand side panels, said side panels at one end having tabs adapted to befolded toward each other and said bottom panel having an extensionprojecting from the end of the body and formed with three sections ofequal width, each equal to the height of the side walls, said top panelbeing formed with a pair of sections and a tab at the end of equalwidth, each of said sections being of a width equal to the height of theside panels and one of said sections being part of the top panelfoldable to extend at right angles to the top panel to form a walloffset from the end of the box, while the other section and the tabconnected thereto are foldable to form with the bottom section and saidside panels an open compartment, the extension on the bottom panel beingfoldable over the tabs extending from the said panel and over the tab ofthe extension from the top panel to hold the parts in their foldedposition, while the third section of the bottom panel is folded flatwiseagainst the bottom of said compartment for locking the parts againstunfolding.
